Book Description
Providing conceptual and practical foundations in scale construction and psychometrics for producers and consumers of social/personality research, this guide covers basic principles, practices, and processes in scale construction, scale evaluation, scale use, and interpretation of research results in the context of psychological measurement. It explains fundamental concepts and methods related to dimensionality, reliability, and validity. In addition, it provides relatively non-technical introductions to special topics and advanced psychometric perspectives such as Confirmatory Factor Analysis, Generalizability Theory, and Item Response Theory. The SAGE Library in Social and Personality Psychology Methods provides students and researchers with an understanding of the methods and techniques essential to conducting cutting-edge research. Each volume within the Library explains a specific topic and has been written by an active scholar (or scholars) with expertise in that particular methodological domain. Assuming no prior knowledge of the topic, the volumes are clear and accessible for all readers. In each volume, a topic is introduced, applications are discussed, and readers are led step by step through worked examples. In addition, advice about how to interpret and prepare results for publication are presented.

Book Description
Scientific research uses concepts (or constructs) and requires means to measure them. Often latent, abstract and not directly observable, these concepts demand special attention. When facing problems related to their operationalization, considerable efforts are required to construe measures that effectively represent the phenomena studied. Measurement in Marketing presents a wide range of ideas to help researchers in the selection, design and validation of measurements of constructs. It analyzes the provisions that must be implemented to allow the transition from a latent conceptual construct to an operational level close to reality, and thus to make possible a fluid, reliable and valid reading of the phenomena observed. This instructive book guides readers through all stages of the implementation of a measure. It is intended for a wide audience, offering examples, summary tables and boxes in order to emphasize the primary information.

Book Description
Four job evaluation factors were used as the basis of rating 10 Air Force specialties. For each factor three different methods were used in constructing the scale: (1) each scale division was defined and illustrated; (2) neither scale division definitions nor examples were used; and (3) definitions were used but the examples were omitted. Ratings by samples of aviation cadets were analyzed for effects of method on mean ratings. For three of the four factors, the mean ratings obtained were not different as a function of the method of scale construction. Methods 1 and 3 were about equally reliable, both yielding more reliable means than method 2. Method 3 is suggested as being the most effective because the task of the rater is somewhat simpler than for method 1 and the reliability is higher than for method 2.

Book Description
"This book is concerned with techniques for the construction of attitude scales. Once a set of attitude statements has been collected, there are two general methods that have been used in the development of attitude scales. One of these methods involves the use of a judging group. The judging group is not asked to respond to the statements in terms of their own agreement or disagreement with them, but rather to judge the degree of favorableness or unfavorableness expressed by each statement. These judgments are then used as a basis for determining scale values of the statements upon a psychological continuum. Once the scale values of the statements are known, subjects can then be asked to express their agreement or disagreement with the individual statements. Attitude scores for these subjects can then be obtained based upon the prior knowledge of the scale values of the statements. The judgment methods for constructing attitude scales differ only in the manner in which the judgments and scale values of the statements are obtained. They include the method of paired comparisons, the method of equal-appearing intervals, and the method of successive intervals. These methods are described in Chapters 2 through 5. A second method of developing attitude scales is based upon direct responses of agreement or disagreement with attitude statements. Since the response methods do not require prior knowledge of the scale values of the statements in any exact sense, a judging group is not necessary. It is sufficient for the response methods if one can assume that the response "agree" to a statement indicates a more favorable attitude than the response "disagree," or vice versa. The response methods for constructing attitude scales include the method of summated ratings and scalogram analysis. These methods are presented in Chapters 6 and 7. Another method for constructing an attitude scale that makes use of both judgments and responses is described in Chapter 8. This method is termed the scale-discrimination technique. It is an early effort upon the part of Kilpatrick and myself at a synthesis of a scaling and a response method for developing an attitude scale. H-technique, as described in Chapter 9, is also a response method. It has as its objective the improvement of a cumulative scale--a kind of scale about which more will be said in the text. In this chapter I have also described another effort at a synthesis of scaling and response methods which, for want of a better name, I have called W-technique. This, in brief, represents the content of this book"--Preface. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Book Description
In the Fourth Edition of Scale Development, Robert F. DeVellis demystifies measurement by emphasizing a logical rather than strictly mathematical understanding of concepts. The text supports readers in comprehending newer approaches to measurement, comparing them to classical approaches, and grasping more clearly the relative merits of each. This edition addresses new topics pertinent to modern measurement approaches and includes additional exercises and topics for class discussion. Available with Perusall—an eBook that makes it easier to prepare for class Perusall is an award-winning eBook platform featuring social annotation tools that allow students and instructors to collaboratively mark up and discuss their SAGE textbook.

Book Description
A majority of large-scale construction and major infrastructure projects are funded by public funds from taxpayers. However, these projects are often subject to severe delays and cost overruns. Large-Scale Construction Project Management: Understanding Legal and Contract Requirements introduces integrated approaches to project management and control mechanisms to effectively manage large-scale construction projects. It explains the contractual requirements and associated legal principles under the latest edition of the leading standard forms of contracts, including FIDIC 2017, NEC4, and JCT 2016. It explains integrated project governance regarding time, cost, risk, change, contract management, and more. Further, it discusses the legal issues of scheduling delays and disruptions regarding the Delay and Disruption Protocol (Society of Construction Law) as well as Forensic Schedule Analysis guidance (American Association of Cost Engineering).

Book Description
The market and policy impetus to install increasingly utility-scale solar systems, or solar farms (sometimes known as solar parks or ranches), has seen products and applications develop ahead of the collective industry knowledge and experience. Recently however, the market has matured and investment opportunites for utility-scale solar farms or parks as part of renewable energy policies have made the sector more attractive. This book brings together the latest technical, practical and financial information available to provide an essential guide to solar farms, from design and planning to installation and maintenance. The book builds on the challenges and lessons learned from existing solar farms, that have been developed across the world, including in Europe, the USA, Australia, China and India. Topics covered include system design, system layout, international installation standards, operation and maintenance, grid penetration, planning applications, and skills required for installation, operation and maintenance. Highly illustrated in full colour, the book provides an essential practical guide for all industry professionals involved in or contemplating utility-scale, grid-connected solar systems.
